Marine Environments, Biodiversity
We are working on the creation and maintenance of the marine environment as a measure to conserve biodiversity and tackle climate change by utilizing our extensive experience and knowledge gained from civil engineering work in coastal and marine areas. To create a future in which people and nature coexist in harmony, we are engaged in research and development based on the technology and experience we have accumulated through our diverse construction experience.
Initiatives to Create and Maintain Marine Environments
To conserve biodiversity in shallow areas and tidal flats, we are working on the development of shallow areas and tidal flats using Calcia stabilized soil, which is easier for organisms to settle than conventional materials. We recycle removed soil for backfilling tidal flats in an attempt to restore them to their pre-construction state, as well as to minimize the impact on tidal flat organisms.
In addition, as a measure against climate change, we carry out evaluation on the carbon fixation as blue carbon in the newly-created shallow areas, in order to contribute to carbon recycling through the creation and evaluation of shallow areas.
Water Purification
By generating water currents with dynamic force, Umisumashi eliminates the stagnation of water flow near the seabed, restores dissolved oxygen, and reduces the elution of nutrients that cause eutrophication and sulfides that are harmful to benthic organisms. It is also effective in improving water temperature by stimulating heat transfer through mixing of surface water and bottom water.
